Stuffing or packing.



UNITED STATES PATENT OFFICE.

ISIDOR MARGOLIUS, OF NORFOLK, VIRGINIA.

STUFFING OR PACKING.

No Drawing.

To all whom it may concern Be it known that I, ISIDOR MARGOLIUS, a citizen of the United States, and a resident of Norfolk, in the county of Norfolk and State of Virginia, have invented a certain new and useful Improvement in Stufiings or Packings, of which the following is a specification.

My invention relates to improvements in stufiings or packings, and it consists in the article of manufacture hereinafter described and more particularly pointed out in the appended claims.

An object of my invention is to produce a cheap and efficient stuffing or packing to be used for stuiiing mattresses, as packing material, as a heat insulating lining, etc.

A further object of my invention is to provide a stufiing or packing which is free from objectionable odor.

A further object of my invention is to provide a stuffing or packing which is comparatively free from objectionable gum or other mucilaginous matter.

A further object of my invention is to provide a stuffing or packing which is substantially undecomposable in the presence of water.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

In making experiments with the bark of the cypress tree, I have made certain dis coveries in regard to the composition of the same which one would not naturally expect. It is known that tanks made of cypress wood impart an odor and a taste to the water which is stored therein, and may even impart a color. The bark of the cypress tree does not present from the outside an appearance to indicate its exceedingly fibrous nature, but I have found by experimenting that, this bark is composed of fibers which are very loosely held together, so that by slight attrition or rubbing of the bark, the fibers may be separated.

In carrying out my invention, I may make use of any of a number of processes which will produce a packing or stuffing having Specification of Letters Patent.

the properties desired. It will suffice to mention one or two processes by means of which the object may be attained.

The bark is selected, and is first boiled to loosen the small amount of cementitious matter which holds the fibers together. One may employ an alkali during this boiling, such as soda ash or soda lye, but such alkali is not absolutely necessary. The boiled bark is then dried, and may be passed through rollers or through decorticating machines so as to break up the bark and to loosen up and separate the fibers. Instead of boiling the bark it may be treated dry. I have found that the fibers can be separated merely by rolling them or twisting them, and therein the cypress bark differs from other fiber bearing plants which require to be combed in order to separate the fibers.

The fibers when separated are collected and form the stufling or packing. This stufiing or packing, contrary to what might be expected, has no odor, and therein it differs from fibers, for instance, of pine needles or other plants or woods which contain oils or rosin. One of the main properties of the packing composed of the fibers of the bark of the cypress tree is that it is practically undecomposable in the presence of water, and for this reason, a mattress, for instance, which has become saturated with water, may be dried out and the pack ing will be in practically the same condition as before it was wet.

Packing made from the fiber of the bark of the cypress tree has a high luster, and in this respect it resembles hair. The packing is a good insulator of heat, and may be used as linings for refrigerators, and in fact, in any case where a heat-insulating packing is necessary.

I claim 1. As an article of manufacture, a packing or stufling material made solely from the hast fibers of the bark of the cypress tree.

2. As an article of manufacture, a packing or stuffing which is substantially non-decomposable in the presence of water and which is made solely from the bast fibers ing a heat insulator, non-odorous, and nonof the bark of the cypress tree. decomposable in the presence of Water, said 3. A packing or stuffing which is nonpacking or stufiing being made solely from 1) decomposable and odorless, and which is the bast fibers of the bark of the cypress 5 made solely from the bast fibers of the bark tree.
